Abstract

This is an essay in the field of mineral processing engineering. The process mineralogy study of a manganese carbonate ore from Hubei Province shows that the main valuable minerals of this ore are kutnohorite, calcimangite and a small amount of pyrolusite with fine monomer dissociation, the gangue minerals are dolomite, quartz and mica. The present manganese carbonate ore belongs to refractory low-grade manganese carbonate ore with high calcium and phosphorus. There are few studies on this type of manganese ore, thereby the treatment process is complicated with the low product grade and the high cost. The mineral processing results of this study reveal that, under the condition of 90% of the products from stage grinding to -74 μm, manganese minerals were recovered by magnetic separation through the process of cleaning mixed concentrate with one roughing and one cleaning tailings, and further enriched by one-stage reverse flotation desilication. Finally, a manganese concentrate with Mn grade of 27.10%, P/Mn ratio of 0.009 and Mn recovery of 58.21% was obtained, which can be mixed with other low-phosphorus manganese concentrates as the metallurgical industrial raw material to meet the industrial requirements.
